Via Kottke’s Quick Links, we arrive at a nifty bit of programming code that can be modified to accommodate any data set and energise one’s presentations and data-visualisations with a bar chart race (like the one we encountered recently). The comprehensive and patient tutorial from Mike Bostock is a study in the power of clear conveyance (very much diametrically opposed to this overly-enthusiastic and persuasive slide deck, via the New Shelton Wet/Dry) and allows one, with some work and investment of time, to harness this sort of bracing animation that has one rooting for the underdog.
